In the NFL – Examines current NFL head coaches years as assistants in the NFL

Post Highlights

  • Cincinnati Bengals head coach Marvin Lewis has had direct connections with 10 other current NFL head coaches; the most by any current head coach.
  • Five current NFL head coaches (Carroll, McCarthy, Morris, Munchak, L. Smith ) have only one direct connection to other head coaches.
  • On average current NFL head coaches have four direct connections to other current head coaches.


Coaching Connections

Every current NFL head coach is connected to another current coach in someway.  On average current coaches have four direct connections to other current coaches.  A direct connection implies that the coaches were on the same team together at some point (includes time as a player and/or coach in the college ranks).
